One ad per affiliate and parent company sharing the same domain per search query.

I read it as 1 ad per domain, from either the merchant or an affiliate.

AdRank will continue to determine which site will be shown.

Which probably means the best performing ad (CTR x CPC) will show. I guess the selection will be made similar to what happens now within an account to determine which ad to show if a keyword is in more than 1 adgroup.

I'm rather pleased with this formula, which doesn't simply forbid multiple accounts per domain. I'm pretty sure we can continu to advertise in different countries form different accounts and not be affected. Hope to see an official email soon.
